We're excited to announce our Engine Control Unit (ECU) Upgrades are now available for the Porsche 718 Cayman/Spyder (982) GT4 4.0L engine with the Bosch MG1 ECU! Expect exceptional gains from this naturally aspirated engine with up to 452-488 HP with 340-361 FT-LBS of torque on tap, depending on octane!

We've extensively calibrated the system to work flawlessly on the track, while retaining safety routines to protect your engine in the most demanding scenarios.

Development vehicles were outfitted with additional sensors, including thermocouples, transducers, and more, along with our high speed direct RAM logging equipment, to feed valuable data to the team for analysis. After exhausting of hours of testing and tuning we created new calibrations that are fine tuned for several octanes and contain hundreds of map changes, with a vast array of safety features built in.
